Windows: Spending a half-hour slowly downloading a huge Zip archive only to discover it's corrupt is a pain. Avoid it with Zip2Fix, a utlity that won't fix corrupt archives, but will extract any and all undamaged files from it.

When it comes to file archiving in Windows, we prefer 7-Zip, and this app is no replacement for it. What Zip2Fix does, however, makes it worth a spot on your hard drive if you run into corrupt archives frequently. Open the app and tell it which archive to run against, and the app will extract as much from it as possible while avoiding the corrupt data. The app is new, so keep in mind that your mileage may vary. Zip2Fix is Windows only, but it's completely free.
